Abstract: The shelves of the Pohai Sea, the Yellow Sea and North Part of East sea of Chinaare a large f1at seafloor which are formed by a series of sedimentary basin and narrowdenuded and planed structual ridges. But the alternated distributional pattern of dif-ferent struetual basin and ridges are obviously distinet. The characteristics of the assem-b1ages of submarine geomorphological types in various structual regions are also very dif-ferent. In addition, though this studied region loeated within the ranges of this typicalagglomerated shelves of Eastern China, the 1ate structual movement still refleets dis-tinetly on the submarine relief and directly affected the exogenic process and existingform of geomorphological types.
